In the beginning, Mark purchased a 3D model of a stock Z car. He used CAD to add the fenders, skirts and splitter. He also had a model of the LS2. After the LS2 was positioned in the model, we know we would have issues with the throttle body sticking through the hood. I my mind I was thinking some kind of scoop to hide it. But Mark had other ideas. He found a TB that would work.
